I've tried everything besides hyperthreading disabled. It seems for my BIOs setting, it is greyed out and I could not change the settings for hyperthreading. Other than hyperthreading, are there other things might cause the problem I encountered?
I have installed the CoDeSys RTE 3.5.17.20 and when I start the PLC I get a blue screen from Windows. Then I tried uninstall it and install the most recent version 3.5.18.20. It still gives the same result with blue screen. I have an Intel CPU with 4 cores. I have been following the Installation and Getting Started.
